Working Theory

If you’re looking for power capability without polluting the environment, have a look at our high flow catalyst converters. Setting up a high flow cat is one of many measures a car enthusiast will take to increase exhaust flow and accordingly gain additional output. During the past two decades, developments in metallurgy and chemistry have enabled tuner companies to make performance cats with compelling performance potential and durability. high flow cat converters increase the engine performance throughout the rev range. performance level-gain is perceptible during acceleration and also becomes exponentially larger as additional alterations are made to the power train, such as high performance cold intake, fuel injection remap or a catback. scrap restrictive factory catalyst that steall horses from your engine.

Will the check engine light be triggered?

No, if catalyst converter is installed to the factory exhaust system then such an exhaust modification committed on the system would not cause the engine to run lean.

Contrary to the common sense, cats are not commodities. There are considerable differences in quality between manufacturers, which results from the different materials that are employed, manufacturing technology, coating materials, and countless further factors. It is generally reasonable to think that cheap catalyst converters are of lower quality, but that doesn't mean that the expensive converters are obviously better. Torque in general, the power you feel at the wheels while driving. Magnum performance converters increase this torque as well as the performance level throughout the entire RPM range. As with pony, the current increase isn't anything incredible, but the solid gains tend to improve as the rest of the vehicle's performance capability. MIG/TIG/Flux required welding though. The progress in manufacturing technology in this industry has led to tuners being able to offer high flow converters that comply with the emission control regulations and bylaws in most of states and countries. Magnum catalyst converters will purify as well, if not better, than your stock catalyst converter.

Magnum high efficiency catalytic converters provide a higher flow capacity than standard cats. They're equipped with a ceramic honeycomb substrate that has been coated with the catalyst metal. The ceramic honeycomb ensures that the exhaust positively comes into contact with the catalyst and that the exhaust gases will flow through it to carry on along the exhaust pipe. These converters are built to endure extreme conditions and come with an integrated heat shield for maximum service life. unleash your swelling horses with our high flow catalytic converter, warranted smooth exhaust flow that’s clean as a breeze. Lower your emissions without spoiling the horses.

These free flow cats are built with both engine performance and harmful vapors in mind. Inside, magnum free flow catalysts are made with enormous ceramic substrates coated in max precious metals. Our technology ensures to strip out the more noxious fumes without employing undue restrictions like the standard converters. Internal catalyst’s honeycomb ceramic substrate maximizes the exhaust flow surface area for significantly reduced restrictions. While at the first sight Magnum catalyst looks like a stock catalyst on the outside, the major difference is hidden in their bellies. Instead of being clogged with large restrictive honeycomb substrate, our low-restriction media gives the exhaust a clear path to your silencer. While harmful vapors is neutralized, power needs are totally satisfied.

Check out Magnum vehicle specific performance catalytic converters Additional technical background information Harmful compounds emitted by a 4-stroke engine The ideal combustion exists only in principle. An Otto-engine's efficiency is not better that 30 up to 45 %. Engine's efficiency and the amount of harmful emissions varies on several factors are related to the combustion taking place in the chambers. The theory described with chemical equation:

Ideal perfect combustion

CnH(2n+2) + O2 --- CO2 + H2O

Realistic combustion

CnH2(n+2) + O2 --- C + H2 + O2 + CO + CnH(2n+2) HC

Since the gas is polluted

N2 + O2 NOx

Pollution, additives

S + O2 SO2 + H2O + H2SO3 The carbon-oxide, nitro-oxides, hydrocarbons and the sulfuric-acids are deemed harmful, therefore their emission level is restricted by emission regulations in most of the countries. For over 30 years the most effective way to reduce the emission of harmful gases and materials to clean and neutralize the combustion products subsequently has been to purify the exhaust gas with one or more catalytic converters fitted on the vehicle's exhaust system.

Oxidation and Deoxidation within the catalytic converter

CO + (1/2)O2 --- CO2 CnH(2n+2) + O2 --- CO2 + H2O NOx + CO --- CO2 + N2 There is many other chemical reactions take place. When it comes down to attain the lowest emissions, electronic control over these chemical processes is a must. In modern engines catalytic converters are controlled electronically by exhaust oxygen sensor.

The oxygen sensor

An automotive oxygen sensor, also known as an O2 sensor, lambda probe, lambda sensor, lambda sonda or EGO (exhaust gas oxygen) sensor, is a small sensor inserted into the exhaust system of a petrol engine to measure the concentration of oxygen remaining in the exhaust gas to allow an electronic control unit (ECU) to control the efficiency of the combustion process in the engine. In most modern automobiles, these sensors are attached to the engine's exhaust manifold to determine whether the mixture of air and gasoline going into the engine is rich (too much fuel) or lean (too little fuel). This information is sent to the engine management ECU computer, which adjusts the mixture to give the engine the best possible fuel economy and lowest possible exhaust emissions.

This converter fit my truck with some modifications. Though it doesn’t have a flat flange or a flange at all in addition it is a couple of inches too short but all the way it wasn’t an issue to add a piece of hose. I own 5 vehicles, order almost all my replacement and performance parts online, and have never had bad experience with Magnum. This cat works like a charm.

i got my two cats on the exact day they said it was going to arrive and installation was easy, except for the old rusty nuts on my stock exhaust system. i am bound new weld-on connection will last as long as i use my suv. if i ever need another car for any of my other cars i will definitely but another one of these. rest assured it fits perfect, look sturdy and top notch quality and you can bolster the horsepower with this high flow cat. mpg is not yet tested acurately but seems to have improoved.

premium quality catalysts, install is a breeze engine got a nice growl when putting the pedal on the metal, my 300C passed (removed) emmissions, no check engine light, lil better take off and more torque from 3000 rpm

Very helpful advice

I wanted to compliment your Mr. Jake Winfield regarding his help and advice concerning my 1996 Jaguar XJR. It appeared that I had cat and O2 sensor problems along with a bad MAF sensor. He walked me through what I needed in order to solve my problems and was patient and helpful all along the way. Kudos to him and your company and I look forward o doing business with you in the future! Douglas Elslager

Bought it for my Xedox. Aside from the fact that the pipe on the stock exhaust did not fit properly and I had to get the old one cut off and welded on to the new one to make it work, and there was no bolt-on flange so I had to add a universal flange with 2 slotted bolt hole, to get it to fit, converter worked pretty well. Noticed instantaneous difference in torque and engine response improved, a slight performance is delivered too.

n an off road Ranger truck powered by a bored 5.0L GMC engine. SES light doesn't come on. Highly recommended. Far superior to the 200 cpi cats all trigger SES and foul after couple months. This converter was purchased after X-mas, and still is on duty. Ranger passed 4 races since then and engine was boiled, magnum cat still sustained excessive heat.
